Effect of Irrigation Regimes and Biofertilizers on Yield and Some Water Relations of Soybean Plant

Abstract

Two field experiments were carried out at El-Karada station of irrigation requirements, Kafr El-sheikh Governorate, during the two summer seasons 2008 &2009, to study the effect of irrigation regimes (irrigating soybean plants at 25, 50 and 75% of available soil moisture depletion (ASMD) and biofertilizers (inoculation soybean seeds with phosphoriene, Rizobial and their mixture, comparing with recommended NPK) on yield and its components, as well as, some water relations of soybean plants. The experimental design is split plot with three replicates, where the main plots were assigned to irrigation regimes, while the sub plots were devoted to biofertilizers.Results showed that both of irrigation treatments and biofertilizers had highly significant effect on yield and its attributes of soybean plants. Irrigated treatments after the depletion of 50% in available soil moisture, gave the highest values of plant height, No. of branches per plant, No. of pods/plant, pods weight /plant, seed weight /plant,1000 seed weight and seed yield (kg/fed) in both growing seasons. Meanwhile, the lowest values of the abovementioned parameters were recorded under irrigation at 75 % ASMD in both seasons. Data also showed that phosphorien + rhizobial inoculation produced the tallest plants; however, the remains aforementioned characters were the highest under application of recommended NPK, followed by rhizobial inoculation in both growing seasons comparing with phosphorien.Seasonal applied water (as an average of the two seasons) was 3451.4, 3006.9 and 2515.5m3 /fed for irrigation at 25, 50 and 75%ASMD treatments, respectively. Irrigating soybean plants at 25% ASMD recorded the highest seasonal water consumption as an average of the two seasons (2272.9m3 /fed), followed by irrigation treatments at 50% ASMD (2074.2m3 /fed) , while the lowest seasonal water consumption was recorded under irrigation at 75% ASMD, and found to be (1859.2m3 /fed). The highest values of crop water use efficiency (0.96&0.84 Kg/m 3 ) and water productivity (0.66&0.58 kg seed yield /m3WA) were achieved under irrigation at 50% ASMD in both seasons, respectively. Meanwhile, irrigating soybean plants at 75% ASMD recorded the lowest values of CWUE (0.56&0.39 kg/m3 ) and water productivity (0.38 &0.29 kg/m3 ) in the 1 st and 2 nd seasons, respectively.

Response of Faba bean to alternate irrigation and cut-off irrigation combined with mineral phosphorus levels and Biofertilizer at North Nile Delta soils.

“…Increasing the seasonal values of water consumptive use under F 2 , F 3 , and F 4 treatments comparing with F 1 -treat., might be due to application of biofertilizers (phosphorien) to seeds which contain bacteria for dissolving phosphorus, this helping to form plants with a conclensed vegetative cover and consequently increasing the values of water consumptive use. These results greatly agree with those reported by Abdel-Aziz (2005), EL-Habbasha et al (2007), Khalifa et al (2013) and Soltan & Marzoka (2015).…”

Effect of different irrigation water levels and bio-minerals fertilization on fruit yield, quality and water productivity of watermelon grown on sandy soil, Egypt.

“…In comparison with yield and its components of F 1 -treatment, F 3 gave an increase fruit number by (4.61 and7.88%), fruit weight by (13.24and 12.94%), fruit yield by (11.72and 12.97%) in the 1 st and 2 nd seasons, respectively. These results are in a great harmony with those obtained by (Omran et al, 2009;ShahdiKomalah, 2010;Khalifa et al, 2013 andSaeed et al, 2015). They reported that the biological fertilizers have a special importance as appropriate replacement for mineral fertilizer through improving of soil fertility providing nutrition requirement of plant and increasing crop yield.…”

“…The irrigation level of I 2 led to an increaseof fruit number plant -1 by (1.12and 4.70%), mean weight of fruit (12.67 and 12.79%), fruit weightplant -1 (14.34 and14.30%) and fruit yield (14.26 and 14.30%) in the 1 st and 2 nd seasons, respectively, in comparison with I 1-treatment.It was noticed from data obtainedthat there was insignificant differences between I 2 and I 3 treatments in both seasons. Increasing watermelon fruit yield under I 2 or I 3 treatments may be due to improving the rate of aeration which increase decomposition of soil organic matter and hence increasing availability of nutrients, therefore, forming healthy plants with good vegetative growth (Khalifa et al, 2013). These results are in agreement with those obtained by (EL-Bassiony et al 2012;Sharma et al, 2014;Pejic et al, 2016;Reddy et al ., 2017).…”

“…Nowadays, under Egyptian conditions, besides limitation of water resources, there is a big problem facing Egyptian agriculture,which is the increasing prices of mineral fertilizers, in addition to their negative effects on soil and water properties by creating mineral pollution problems and limiting the reuse of drainage water again.Such problem could be solved by using Biofertilizers instead of mineral ones, which is a profitable from the economic of view and effective in reducing pollution of soil (Salantur et al, 2005 andAbbas et al, 2006) Biofertilizers have several advantages over chemical fertilizers, they are non-pollutant, inexpensive, utilize renewable resources, their ability of using free available solar energy and they use atmospheric nitrogen and water (Mahato et al, 2009;Wu et al, 2005;Banerjee et al 2006 andMorsy et al 2008). Also, the biological fertilizers have been shown to have a special importance as appropriate replacement for chemical fertilizers, through improving of soil fertility providing nutrition requirement of plant and increasing crop yield (PoraasEL-Din et al, 2008, ShahdiKomalah, 2010Khalifa et al, 2013 andSaeed et al, 2015). Organic material such as poultry manure (PM) is identified as a suitable organic fertilizer.…”

“…Additionally, it has been demonstrated that biological fertilizers are particularly important as a suitable alternative to mineral fertilizers by enhancing soil fertility, meeting plant nutrition needs and increasing crop yield. (Poraas EL-Din et al, 2008, Khalifa et al, 2013, Saeed et al, 2015and Khalifa, 2020. Under limitation of water resources, high prices of mineral fertilizers and fatal environmental pollution a big problem faces the Egyptian Agriculture.…”
